Improvement in hat-forming machines



UNITED STATES PATENT @Erica H. N. SWIFT, OF MATTEAWAN, NEW YORK.

IMPROVEMENT IVN HAT-FORMING MACHINE-S.

Specification forming part of Letters Patent No. 53,196, dated March 13, 1866.

.To all rwhom it may concern:

Be it known that I, H. N. SWIFT, of Matteawan, in the county of Duchess and State of New York, have invented anew and Improved Hat-Forming Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in whichy Figure 1 represents a side elevation of this invention. Fig. 2 is a plan or top view of the same, partly in section. Fig. 3 is4 a diagram Y showing` the relative position of the connection rod and crank when the driving-wheel is former at half-motion, while the motion of the driving-wheel continues without interruption, and the operation of banding or forming the brims of the hats can be effected without stopping the vibrating of the frame 5 third, in coinbining, with the sun-and-planet gear, an adjustable wrist-pin.- in such a manner that the speed of the vibrating can be increased or dccreased at pleasure while passing the center.

A represents a platform or bed-plate, which supports the several working parts of my machine. From this bed-plate rises a standard, B, which serves to steady the upper part of an oscillating frame, C, the lower part of which has its bearing on a pivot, a, and to which the desired oscillating motion is imparted by means of an arm, b, which extends from the lower part of said frame and connects by a rod, c, with the driving-wheel d.

In the frame C are mounted the rolls D, to which a revolving motion is imparted by suitable bevel-gear in the usual manner.

The drivingwheel d, which in ordinary hatforming machines is mounted on a vertical arbor, l have secured to a horizontal shaft or stud, c, which is fastened in a standard, f, rising from the platform A, and by this arrangement the vibrations of the oscillating frame are equalized, which is not the case with hatforming machines of the ordinary construction, in which the driving-wheel revolves on a vertical shaft, as will be readily understood by referring to Fig. 3 ot' the drawings. Ii' in in this tigure e* represents the center of the driving'wheel dit, D* the arm which is connected to the oscillating frame and swings on the center ait, and c* the connectingrod, which is secured to the eccentric wrist-pin w* on the driving-wheel, the outer end of the arm b* will swing through t-he arc l 2 while the wrist-pin w* travels from 1'* to 2*, and through the arc 2 3 while the wrist-pin travels from 2it to 3*; but While the wrist-pin travels from to 4* the arm biF swings through the arc 3 4, (which is much larger than the arc 2 3,) and while the wrist-pin travels through the last quarter ot' its circuit, from 4i to 1*, the motion ot the arm is limited to the arc 4 1.

In my machine, where the driving-wheel is placed in a vertical position, the'motion imparted to the arm b is the saine while the wrist-pin w passes the upper haltl of its circuit as it is while said wrist-pin passes the lower halt', and the vibrations oi' the frame G, which carries the 'ormers. are equalized.

The wrist-pin w in my machine is secured to a plate, g, which is fastened to a pinion, h, mounted on a stud, i', which projects from the driving-wheel d, as shown particularly in Fig. 2. The pinion lt gears in a cog-wheel or toothed rim, j, which is firmly keyed or other wise secured to the stud c, on which the driving-wheel revolves, and by these means a sun and-planet motion is obtained, and the vibrating of the oscillating frame C becomes slower while passing over the center in proportion as the wrist in plate y, which is attached to the pinion, is thrown oft' the center of said pinion, thus giving time i'or the operation ot' banding or forming the brim without stopping the vibration, which is necessary on ordinary niachines. This plate y is secured to the pinion h by means of screws 7c, which pass through slots in said plate, so that the position of said plate can be changed and the wristpin can be adj usted so as to cause the oscillating frame to sweep through a greater or smaller arc, and

by these means the speed ofthe vibration can be increased or diminished at pleasure.

Instead ot' the sun-and-planet gear a calngroove ot' suitable forni might be used and the same effect could be produced.

What I claim as new7 and desire to secure by Letters Patent, is-

1. Placing the drivin g-Wheel l of a hat-forniA inzg` machine in a plane parallel with the axis of the pin or stud a on which the frame C oscillates instead of at right angles to the saine, substantially as and for the purpose described.

2. The sun-and-planet gear 7L j, or its equiva- Witnesses:
